Resumo: This experiment was conducted to evaluate the effects of three production systems on the weightgain of Ille de France male lambs within 15 to 20 days of age for a period of 63 days. The animals were assigned to complete randomized design in three treatments (T). In T1, 10 animals were kept with their mothers in an area of ryegrass paddock without supplementation. In T2, 8 animals were kept in confinement and feeding withconcentrate in pellets with 22% GP and whole ryegrass at will. Also they had access twice a day to their mothers’milk . In T3, 10 animals were kept together with their mothers in a ryegrass pasture with free access to creepfeeding with concentrate in pellets with 22% GP. The T2 got higher (P < 0,05) live weight gain than T1 and T3 in the period between 33 and 64 days of age. There was no significant difference (P > 0,05) in the periods of 17-32 days and 65-80 days of age between T2 and T3 treatments, but they differ from T1. The gross margins obtainedwere of R$ 54.25; R$ 85.86 and R$ 66.99 for treatments 1, 2 and 3 respectively

Cada sistema correspondeu a um tratamento (T), sendo o T1 formado por dez animais que permaneceram com as mães em uma área de 0,7hade pastagem de azevém e sem suplementação alimentar. O T2 formado por oito cordeiros confinados e alimentados com ração contendo 22% de proteína bruta e forragem de azevém à vontade. Os animais também tiveram acesso ao aleitamento de suas mães entre 12 e 14 horas e à noite. No T3, dez animais permaneceram todo o tempo com as mães em pastagens de azevém e acesso privativo à ração peletizada com 22% de proteína ("creepfeeding")4. O T2 teve o maior ganho de peso vivo no intervalo entre 33 e 64 dias de idade quando comparado comT1 e T3 (P < 0,05). Nos intervalos de 17 a 32 e 65 a 80 dias de idade, T2 e T3 não diferiram entre si (P > 0,05), porém ambos diferiram do T1 (P < 0,05). As margens brutas foram de R$ 54,25, R$ 85,86 e R$ 66,99 para T1, T2 e T3, respectivamente, evidenciando o T2 como o de maior rentabilidade.
